9. For each of the following homomorphisms, compute the indicated quantities. (a) (6 points) Let o : Z - GL2(R) be the group homomorphism determined by $(1) = ( ; -? ) Determine ker($), the kernel of o, and compute d(8).(b) (6 points) Let y : Z x Z - Z be the group homomorphism determined by y((1, 0)) = 3 and y((0, 1)) = -2. Determine the ker(y), the kernel of y, and compute y((4, -5))
